Real-World Examples of Latitude and Longitude in Action

📚 Quick Study Guide

• 🌍 Latitude: Measures north-south position on Earth. Lines of latitude are called parallels. The equator is 0° latitude.
• 🧭 Longitude: Measures east-west position on Earth. Lines of longitude are called meridians. The prime meridian (Greenwich) is 0° longitude.
• 📍 Coordinates: Locations are specified using latitude first, then longitude (e.g., 34°N, 118°W).
• 🌐 Great Circles: The shortest distance between two points on Earth lies along a great circle.
• 🗺️ Degrees, Minutes, Seconds: Each degree is divided into 60 minutes, and each minute into 60 seconds (e.g., 34° 05' 20" N).
• ⏱️ Time Zones: Longitude is used to define time zones; each 15° of longitude corresponds to a one-hour difference in time.
